LlNOTYPE-MATRIX.

SPECIFICATION forming part of Letters Patent 0. 752,179, dated February 16, 1904.

Application filed August 20, 1903.

To all whom it may concern.-

Be it known that I, HANS PETERSEN, a citizen of the United States, residing at Minneapolis,'in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Linotype-Matrices;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to linotype-m'atrices, and has for its object to improve the same, as hereinafter noted; and to such ends the invention consists of-the construction and arrangement of parts, as hereinafter described, and defined in the claims. 7

This invention is especially directed to the improvement of matrices for use in what is known as the Mergenthaler linotype-machines, but is nevertheless capable of a more general use. In these so-called linotype-machines there is employedabank of characterkeys comprising about ninety keys. About ten of these keys are appropriated to characters which for a large class of work are not very important, and hence may be dispensed 'with. A larger number than ten of thesecharacter-keys cannot, however, be dispensed with or assigned to any other characters than those which are usually found on the keyboard.

There is a class of work found especially in advertisements where relatively large numerals or other characters are placed in line with the two rows of relatively small characters, so that one-half of the former will aline with each row of the latter. Otherwise stated, the upper halves of the relatively large numerals must be cast on the same linotype-bar with the upper row of relatively small characters, and the lower halves of such large numerals must be cast on the same linotype-bar with the lower row of relatively small characters. To provide for this work, it has hitherto been proposed to form the matrix of each relatively large numeral or character in sections and to place the sections ofsuch matrix on different matrix-bars- Such arrangement,

. after more fully appear.

s rial No. 170,111. (No model.)

words, it would require for such purpose the appropriation or use of twice as rmany :keys

onthe'keyboard as there are sectional characters. .This,.as already pointed out, is not practicable, for the reason that it would; r'e-Y quire either the use of akeyboard having too great a number of keys or would rob the standard keyboard of too many ofits characters. tion Iprovide matrix-bars each of which 'is formed with the two sections of the same sectional or two-part matrix of the character to which the particular matrix-bar is assigned. By this arrangement the employment often sectional or two-part numerals or characters will require the use of but ten keys of the keyboard to control the same, as will herein.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figures 1 and 2 are plan views showing groups of assembled matrix-bars. Fig. 3 is a broken section on the line 00 of Fig. l, and Fig. 4: is a plan View showing the print or impression made by two linotyiae-bars cast from the matrices assembled as shown in Figs. 1 and 2. I

In the drawings the numeral 1 indicates the matrix-bars, certain of which are provided with relatively small character-matrices 2 and others of which, in accordance with my invention, are provided with the sectional matrices a. and (0 The matrices a and a on a Hence in accordance with my inven'-' given bar lare located directly one over the seen that the upper half-sections a of these matrices are assembled in line with the matrices which spell the word house. While these matrices are thus assembled a linotypebar will be cast therefrom. Thereafter the lower half-sections a will be assembled in line k with the matrices which spell the word rooms, as shown in Fig. 2, and the second linotype-bar will be cast therefrom. The two linotype-bars thus cast being placed together will produce a print shown in Fig. 4. It will of course be understood that in the machine which controls the matrix-bars the same key will be struck for a sectional character regardless of whether'it is the upper or lower section of the character which is to be assembled at the casting-point and that by some suitable means, not necessary for the purposes of this case to consider, the matrixbars will be moved endwise in the one instance to bring the proper section of the matrix to the casting-point. For instance, we will assume that under the control of the character-keys the matrix-bars will be assembled as shown in Fig. 1, so that the upper sections of the divided matrices will be brought to the casting-point or opposite the mold. If this is the case, then it will, as is obvious, in order to bring the lower sections of said matrices to the casting-point, be necessary to move such matrix-bars endwise, as shown in Fig. 2.

From what has already been stated it is thought to have been made clear that by the arrangement of the sections of the matrix of a given character on the same matrix-bar the capacity of a linotype-machine is greatly increased practically without increase in the cost of such a machine, and, furthermore, that by my invention I have made a class of work practicable which has not hitherto been satisfactorily accomplished on linotype-machines of the character above noted.

It will be observed that the essence of the invention resides in forming in one matrix two cavities separately usable and in such relation to each other that a character produced on one slug by one of the cavities will aline with, join, or form a continuation of a character formed on a second slug by the other cavity, the effect being to produce a composite character when the two slugs are brought together. The form or design of the composite character, whether it is a letter or other character or other design, is manifestly immaterial, provided the portions of the respective slugs are formed by different cavities in the matrix and adapted to join when the slugs are placed in contact.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. A matrix-bar having thereon supplemental sections of the same character.

2. A matrix-bar having on the one face the two supplemental sections of the matrix of the same character, substantially as described.

3. Amatrix for a linotype or analogous machine,containing two dissociated complementary parts of one character, whereby it is adapted to produce, on successive slugs, character members which will register and jointly form a large character when the slugs are brought together.

4. A matrix for a linotype-machine, containing unconnected complementary parts of one character, said parts alined lengthwise of the matrix, whereby two slugs may be produced, with their character members in exact registration.

5. A linotype-matrix having two separatelyusable cavities so related that the characters cast in respective cavities on successive slugs will join and form a composite character.

In testimony whereof I afiix my signature in presence of two witnesses.

HANS PETERSEN.
